I think this article should be merged with satellite navigation systems, and redirected there. Any objections? -- Michaelfavor 16:10, 8 December 2006 (UTC)
GNSS is the accepted generic term for GPS and its peers. The taxonomy is as follows:
It is OK to keep SNS as an overview article that covers the history up to GPS. - —Preceding unsigned comment added by 70.198.253.77 ( talk • contribs) 17:42, 8 December 2006
I have searched the web to see if this is an existing concept, but can find no support. It appears to be original research. The only thing I found seems to be an opposing opinion on the classification.
“ | The GNSSP subgroup concerned with GNSS service levels convened on the 22nd and 23rd of April 2002. The subjects of discussion were Working Papers that presented a proposed GNSS classification scheme, service levels and also discussed how to use such a scheme in an operational environment. The group met following discussion in Working Groups A and B that had concluded that the classification scheme and service levels appeared unnecessary and that the added value needed clarification. | ” |
Does anyone else know of support for this component of the article? - Davandron | Talk 14:19, 11 January 2007 (UTC)
This section desperately need updating. The first generation is already fully operational with 3 satellite in orbit. The second generation Beidou system currently have 1 experimental satellite in orbit as of Feb 07, with new launches planned in a few weeks time. I will add these information and more to this section if no one object. Yongke 17:52, 29 March 2007 (UTC)
Regarding this revert [1], I wonder if GLONASS does not stand for "GLObal NAvigation Satellite System". -- Sjhan81 03:56, 30 July 2007 (UTC)
Since the articles are now merged, with GNSS inheriting the content, I've copied over the SNS discussion topics.
DGPS only "eliminates the military advantage" as long as your DGPS transmitters are usable. DGPS transmitters can be either:

It's not accurate to say that "Some Japanese" started transmitting DGPS data and implying that this was some sort of hack, without mentioning all of the other parties (and governments) that also broadcast DGPS signals.

The military resisted for most of the 1990s, but SA was eventually turned off in 1999.
An anonymous user (218.101.54.21), with no other edits, changed this date from 1999 to 2000, does anybody have a source that can confirm the year? Should the change be reverted? Edward 09:10, 15 Sep 2004 (UTC)
Selective Availability was officially activated on Mar. 25, 1990 then deactivated on May 2, 2000. These dates are according to 'Introduction to GPS - the Global Positioning System' by Ahmed El-Rabbany 2nd Ed. pp. 45-46. El-Rabbany gives a citation for each date:

The GLONASS article says that the GLONASS system is (or soon will be) once again fully operational. Should we change that in the text of this article? -- WhiteDragon 20:33, 26 September 2005 (UTC)
It's TOTALLY WRONG to remove the GNSS link and link this to “Satellite navigation system” as the main term for this page is GNSS, which will replace the term “GPS” in long terms anyway. GPS is out and GNSS is in as most receivers will be GNSS (Global Satellite Navigation Systems) which includes Galileo, Glonass and the elderly and outdated GPS, but also Japan is soon introducing it’s own GNSS.
Having the European Community launching the new Galileo satellites gives totally new aspects in navigation and in this way Europe has beaten USA in space navigation systems for at least 15 years to come. Galileo has a better atomic clock, and while GPS is only based on 2MHz, Galileo will have a much better bandwidth with its 20MHz, so more data and functions will be introduced with Galileo.
Suggestion: Link this article into GNSS, which would be definitely right, unless Wikipedia pages are American centric? —The preceding unsigned comment was added by 202.5.89.119 ( talk • contribs) 05:32, August 28, 2006 (UTC)

I have tagged both Satellite navigation system and Global Navigation Satellite System for merging. As outlined above, the term GNSS is the consensus standard of consensus standards organizations, therefore it is the correct term for an encyclopedic entry. Dhaluza 03:09, 9 December 2006 (UTC)
The opening sentence is poor - the terms "early" and "predecessor" are meaningless without some prior context. This article should start with a description of the subject, before starting on its history! -- Pfold 14:33, 16 October 2006 (UTC)
In the late '60s/early 70's there was a satellite navigation system called SatNav. The US Navy used it and it was expected to replace Loran. It wasn't as successful as hoped and I believe it is obsolescent. Lately, the term "sat nav" has become a popular generic term for GPS. I think this article should be updated to include information about SatNav enough to eliminate any ambiguity. Knotserious ( talk) 21:01, 24 October 2008 (UTC)
The GLONASS article says that GLONASS is operational, like GPS. Should the GLONASS section of the Satellite navigation article be moved under the Operational heading? -- 50.48.104.164 ( talk) 18:32, 26 June 2011 (UTC)
What is for You higher term? GPS or GNSS? Is GPS system just a part of the GNSS or You think that all positionig systems like GLONASS or in future Galileo, Beidou can have the prefix GPS (e. g. GPS Glonass, GPS Galileo ... )?! Thanks! —Preceding unsigned comment added by 78.0.215.8 ( talk) 20:24, 7 December 2010 (UTC)
The chart under the #Comparison of systems section includes a row for "Evolution". This isn't defined, nor does there appear to be an entry for such a use of the word at Evolution (disambiguation).
What does it mean?

The result of the move request was: page moved. Appears uncontroversial, despite several previous moves. Rationale is a bit lightweight but valid. Andrewa ( talk) 06:17, 28 March 2011 (UTC)
Global navigation satellite system → Satellite navigation — Far more common term. -- G W … 22:50, 15 March 2011 (UTC)
Particularly since this article seems to state unequivocally that civilian satellite navigation systems are regional and not global in scope or implementation. — Preceding unsigned comment added by Da5id403 ( talk • contribs) 20:17, 30 October 2012 (UTC)
One column that needs to be added to the Comparison of GNSS systems is the accuracy (i.e. resolution) of each system. Pma jones ( talk) 07:10, 29 January 2010 (UTC)
does the global navigation satellite system have cameras —Preceding unsigned comment added by 168.172.1.4 ( talk) 13:15, 20 July 2010 (UTC)
Another omission is there are receivers that can combine multiple satellite systems for higher accuracy and/or better coverage. Doyna Yar ( talk) 06:52, 30 December 2013 (UTC)
